Your version has the typical terrible jagged artifacts that Prime avoids. Other than that, too much sharpening.

I didn't add any sharpening beyond whatever default ACR applies Why not play along and show me how much better DXO does , I am trying out 2.2 at the moment

I couldn't actually see any 'terrible jagged artefacts' -- why I asked for side-by-side examples too.

Here's a render from PhotoLab. I used Adobe's E-M1 II DNG profile. As always, "Smart Lighting" Off. It's not hard to see what I mean, but I'll include a side by side picture as well.

Left: Adobe, Right: DxO

(Also, I found it very frustrating to use that 'hair' image as an example, almost impossible to know what is in focus and what is blurred due to out-of-focus vs NR)

Your comment applied to James' version, so here is side by side:

Left James, Right DxO PRIME


Now adding a side-by-side of your PRIME vs my RawTherapee NR

Arrows point to colour artefacts with PRIME, that are nice and clean with RawTherapee

Although both images have artefacts in the dark background to the left of the arrows, IMO your PRIME is the more chunky, granulated and 'noisy' in that area.

Rawtherapee is free open source software, but my point is not 'which wins', but IMO for you to say that PRIME is miles in front on a pedestal all by its own is not right.

Personally I am not a fan of using strong global NR in any case: I prefer to be light-handed with global NR at the raw stage, then only apply NR and sharpening judiciously to selected areas, to a degree that is appropriate for the intended exported image size and purpose.
